Well, Naruto's relationships would be in flux. His peers might be divided. Some might think he's being disrespectful to the ninja tradition and distance themselves from him. But others, like Shikamaru, might be intrigued by Naruto's new - found independence. Naruto's relationship with the Hidden Leaf as a whole could be at risk. But at the same time, this could be an opportunity for him to build deeper, more meaningful relationships with those who truly believe in him as a person rather than just a ninja with a headband. He could form new alliances and strengthen old ones in unexpected ways.
His relationship with Sasuke might change. Sasuke might initially be confused or even critical of Naruto without his headband. But as Naruto shows his determination without it, Sasuke could gain a new respect for him. With his friends like Sakura, they might be more protective of Naruto, fearing that others will target him without the symbol of his ninja status.
With Sakura, Naruto's attitude could shift. Instead of being the goofy, love - stricken Naruto she's used to, he could become more distant. He might be so focused on his training with Zabuza that he doesn't have time for Sakura's attempts to get his attention. This could make Sakura feel rejected and lead to some tension between them.
Naruto's friends might be initially suspicious of the new skills and attitude he gets from Slade's training. For example, Sasuke could see Naruto's new combat style as too ruthless and this could create tension between them. Sakura might worry that Naruto is getting too influenced by a dangerous figure. However, if Naruto can show that he's still the same person at heart, they could gradually accept his new abilities.
One possible plot could be Naruto feeling a sense of loss and vulnerability without his headband. Maybe he loses it during a battle and has to prove himself all over again without that symbol of his ninja identity. He could struggle with how others in the village view him now that he doesn't have the recognizable headband.
His relationship with Sasuke would be very different. Instead of being a peer trying to bring Sasuke back, he'd be more like an older figure. He might be someone Sasuke looks up to or even fears because of his power and knowledge at that age. Naruto would also have a different relationship with Kakashi. He'd probably be more of an equal to Kakashi in terms of combat ability and strategic thinking.
Well, in terms of his relationship with Sasuke, it could go either way. Sasuke might see Naruto's transformation into the Kyubi as a challenge to his own power and strive to become stronger. Or, he could be intrigued by this new form of Naruto and consider teaming up with him again. Regarding his relationship with the villagers, those who once feared him for having the Kyubi inside him might now fear him even more in his Kyubi form. However, some of the younger generation might look up to him as a symbol of strength. And his relationship with Hinata would also be affected. Hinata might be more determined to protect Naruto, but also feel a bit inadequate compared to his new - found power.
In terms of his relationship with the villagers, those who once bullied him for being an orphan and having a different look (with his blond hair) might be even more hostile if his red hair makes him stand out more. However, there could also be some villagers who see his red hair as a sign of something special and start to respect him more, which could lead to a shift in how Naruto views the village and his place in it.
His relationship with Sakura would change a lot. Sakura might be more protective of Naruto as a cat, seeing him as a cute and vulnerable creature. She might take on a more motherly role towards him. With Kakashi, Kakashi would probably be amused by Naruto's cat form at first, but then he'd start to worry about how to turn him back. And as for his friends in general, they'd have to communicate with him in different ways, like through body language and meows.
His relationship with Sasuke would be greatly affected. Sasuke might see Naruto as a completely different person now that he has become the Nine - Tails. There could be a sense of fear or at least a new level of caution from Sasuke. They might have to re - establish their bond, as Naruto's new form could be a threat in Sasuke's eyes.
Naruto's relationship with the younger generation would be very different. As a Jounin, he would be a role model. The kids in the village would look up to him even more. He could inspire them to work hard. His relationship with Hinata might also evolve. Maybe he would finally have more time to focus on their relationship now that he has achieved a higher rank and more stability in his ninja career.
His relationship with his sensei, Kakashi, would change significantly. Kakashi would be more cautious around Naruto, not fully understanding the implications of his new vampire state. At the same time, he would try to guide Naruto in controlling his new powers. Naruto would look to Kakashi for help but also feel a sense of isolation as he realizes he's different from the other ninjas. And his friendships with the other Konoha 11 would be strained. They might be afraid of him, or he might push them away to protect them.
